This Mystery Rocks! By Cyntha Schlagel

1The Drifting Rocks are a strange phenomenon still unexplained by science. 2Located in Death Valley, California, the rocks sit on hot, flat ground. 3Unlike normal rocks, they have trails etched behind them as if they have traveled across the sand. 4Some trails are only a few feet. 5Some trails are over a half a mile long. 6Each trail is as baffling as the next.

7The variety of rock movement has baffled scientists for decades. 8Some rocks seem to roll as they move forward. 9Some take unexplainable routes. 10Large ones have traveled past small ones that have stayed still. 11Some scientists suggest that the rocks are pushed by wind. 12Others believe they slide on small amounts of ice or mud. 13So far, research has not confirmed any theory.

Which choice best describes how the author organized information? (4 points)

Group of answer choices

A. Cause and effect

B. Chronological order

C. Fact by fact

D. Problem-solution

C. Fact by fact

Explanation:

Let's use process of elimination.

A. "Cause and effect"

Is there any "cause"? We definitely see an "effect" of some sort in the trails of the various sizes of rocks, but we don't see a "cause". In fact, the passage says that "so far, research has not confirmed any theory", which means scientists don't know the cause of this phenomenon. A is incorrect.

B. "Chronological order"

Chronological order usually is used when we see something historically, involving dates and times. However, the passage is simply a long description of how the rocks appear, move, etc, rather than indications of when they were discovered or a step-by-step explanation of how they were formed. B is wrong.

C. "Fact by fact"

We can see that throughout the passage, the author is essentially listing out fact after fact about the Drifting Rocks. C is correct.

D. "Problem-solution"

There is definitely a "problem" in that scientists don't know why these rocks move in the way they do. However, just like in A, we don't have a "cause" or a "solution" to this problem.  D is incorrect.

The answer is C.
